Automatically remove Examples section of pull request template when this repo is used to create a new repo

I found this article which uses a GitHub workflow to set up a repo created from a template. The workflow will run when the repo is first created, force-push to itself to clear the version generated by GitHub, then delete the workflow. This would be handy to automatically remove the Examples section of the pull request template, a step that is often forgotten: https://github.com/MetaMask/core/pull/1162. Taking things a step further, we could also use it to actually write a new pull request template on creation as per https://github.com/MetaMask/core/pull/1162. That way this module template would have a version of the pull request template specific to it and any newly created repos would have their own version, minimizing confusion when submitting new pull requests to this repo specifically.

Start with the GitHub workflow approach described in the linked MetaMask/core pull request and inspect how this repository stores its pull request template. Define the workflow's creation, self-update, and cleanup behavior, then verify that a repository created from the template receives a module-specific pull request template without the Examples section.
